lNCANDESCENT-LAMP FIXTURE.

SPECIFICATION forming part of Letters Patent No. 441,877, dated December2, 1890.

Application filed August 9, 1890. Serial No. 361,594. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK LEWIS, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new I mprovement inIncandescent Electric Lamps; and I do hereby declare the following, whentaken in connection with accompanying drawings and theletters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in-

Figure 1, a view in side elevation of an incandescent electric lampprovided with my improvement; Fig. 2-, a detached plan view of thelampremoved from the shade andshade holder.

My invention relates to an improvement in incandescent electric lamps,the object being to provide simple and convenient means for turning thecurrent on and off a lamp pro vided with the usual flat keyorthumb-piece, and primarily designed to be operated by hand, but hung orplace so as to be not readily accessible for such operation.

With these ends in view my invention consists in a two-armedoperating-lever having its central portion or body adapted to fit overor embrace an ordinary flat key or thumbpiece.

As herein shown, my improved device consists of a body portion A open atone side and having an elongated opening conforming to the transversesection of the key or thumbpiece B, over which the said body portion isslipped, being secured in place, as herein shown, by means of aset-screw C, which will preferably be employed, although I might makethe operating-lever of spring metal and secure it in place by itselasticity. Two arms D and D, projecting from opposite corners and endsof the said body portion and preferably formed integral therewith,extend outward and inward at an angle to each other, and are provided attheir outer ends with eyes E for the attachment of long chains F, whichextend down into convenient reach. These chains are provided at theirlower ends with rings G, and may, if desired, be replaced by lightcords.It will be apparent that by oper' ating one chain or the other the keyor thumb-piece may be given a quarter-turn and the current turned ontoor 01f the lamp.

It will be understood that my improvement is applicable to anyincandescent electric lamp having a fiat key or thumb-piece, whichrequires no modification or change for the application of myimprovementto it. The body portion of the device may, however, be formed indifferent ways, and the arms may be bent and inclined with respect toeach other as is found most convenient in use.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with an incandescentelectric lamp having a flat key orthum b-piece for turning the current OE and on, of a twoarmedoperatingdever having a central body portion provided with an openingadapting it to be slipped over and secured to the thumbpiece or key, andoperating chains or cords attached to the outer ends of the arms of thelever and hanging down within easy reach for turning on and off thecurrent, substantially as described.

FREDERICK LEWIS.
